AU159: Determination of Volcanic Gases as Anions in Caustic Solutions Using AutoNeutralization, Automated Dilutions, and a Reagent-Free Ion Chromatography System
Description
The type, amount, and ratios of volcanic gases characterize and can predict impending volcanic activity and its intensity. Changes in CO2 concentration, SO2-CO2 ratios, or halide gas composition may indicate impending volcanic eruptions. Previous analyses indicate that volcanic gases are primarily composed of CO2, water vapor, and SO2 with trace amounts of arsine and halide gases. The samples are diluted by AutoDilution to determine the major components as anions and neutralized by AutoNeutralization to determine the trace gases as anions.| Market: | GeoSciences |
